About the Project

In the last few decades, diaphragm-based photonic sensors have been widely employed in industrial and biomedical applications to measure pressure, temperature, and acoustic waves etc.

These sensors work on the principle of Fabry–Perot interferometer (FPI) and are mostly comprised of optical fibres. The motives behind their use are their compactness, high sensitivity, high-frequency response, immunity to electromagnetic interference, and they can also be multiplexed in large numbers on a single fibre, with very high data rates at remote locations. this research is to introduce a novel design of a temperature compensated diaphragm based Fabry Perot interferometric sensor. The research includes the theoretical aspects of the design, modelling and simulations, fabrication, and characterization of the sensors. For compensation of the temperature changes while measuring the pressure, a multiparameter sensing feature of the sensors will be introduced where the sensors will have the capability to sense temperature and pressure in the same instant.


The main objectives of this project are as:

·      To investigate suitable and biocompatible materials for diaphragm

·      To fabricate the optical fibre sensor for pressure sensing including the adjustment of thermal effects

·      To maximise the sensitivity and longevity of the sensor

·      To develop a sensor that is compatible for integration with IoTs and sensor fusion in biomedical applications under the paradigm of connected health.

·      To publish the results in renowned conferences and international journals.

Completed applications should be submitted to to the Research office, Atlantic Technological University Sligo Campus,
